Shrinkage Curve: Experimental Study and Modelling

Measuring and modelling the soil shrinkage characteristic curve

The macroporosity, and to a lesser extent the microporosity, of swelling and shrinking soils is affected by their shrinkage behaviour. The magnitude of the changes in bulk volume in response to changes in water content is usually described by the soil shrinkage characteristic curve (SSCC), i.e. the relation between the void ratio and the moisture ratio. At present, many techniques have been des...

Curve and Surface Smoothing without Shrinkage

For a number of computational purposes, including visualization of scientific data and registration of multimodal medical data, smooth curves must be approximated by polygonal curves, and surfaces by polyhedral surfaces. An inherent problem of these approximation algorithms is that the resulting curves and surfaces appear faceted. Boundary-following and iso-surface construction algorithms are t...

Modelling and Experimental Study of Wax Deposition in Transportation Line Using a Flow Loop System

Experimental study and modelling of date palm fibre composite acoustic behaviour using differential evolution algorithm

Background and aims: In recent years, in most countries of the world, the provision of a calming environment without disturbing noise has become a need, which has subsequently led to significant growth in noise control techniques. It is now well documented that prolonged over-exposure to the excessive levels of environmental noise not only induces disabling hearing impairment but also contribut...

Numerical and Experimental Investigation of Solidification Shrinkage

The solidification heat transfer, melt convection and volume shrinkage in the casting of an energetic material are analyzed through numerical modeling and experimental investigation. The shrinkage resulting from phase change is considered through the volume of fluid method. The model is validated against an analytical solution and then applied to study the volume contraction during the casting ...

Modelling Lorenz curve

There has been a large number of studies in which the scientists have built models for income distributions. As an alternative, some have built models for Lorenz curves. The step from Lorenz curve to distribution function is more difficult than the step from distribution function to Lorenz curve. There is a difference between advanced and simple Lorenz models. Advanced models with several param...
